Problems solved by technology

One feature of this strategy is that it is suitable for driving on comprehensive road conditions. If the driving conditions of the last tank of fuel and this tank of fuel are a single working condition with different fuel consumption, the mileage deviation will be large, and even the mileage will change in the later stage of driving. The phenomenon that the mileage varies by several times cannot accurately reflect the driving distance of the remaining fuel in the car

Embodiment Construction

[0033] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0034] The present invention aims at the problem that the calculation of the cruising range of the prior art is quite different from the actual mileage, which brings inconvenience to the driver. The volume, the fuel injection volume of the engine, and the remaining fuel volume of the motor vehicle are used to obtain the target remaining fuel volume, and the target average fuel consumption is obtained by integrating the average fuel consumption of the last tank of fuel, the average fuel consumption of the current tank of fuel, the theoretical fuel consumption, and the instantaneous fuel consumption at the current time point. Fuel consumption, combined with the target remaining fuel and the target average fuel consumption to obtain the real-time mileage of ...

Abstract

The invention provides a method and device for calculating the motor vehicle driving mileage and an automobile and relates to the technical field of automobiles. The calculating method comprises the step of obtaining the residual oil mass of a target according to the oil tank capacity of a motor vehicle, the fuel injection mass of an engine and the residual oil mass of the motor vehicle, the step of obtaining the average oil consumption of the target according to the average oil consumption of the oil in the last tank, the average oil consumption of the oil in the current tank, the theoretical oil consumption and the instant oil consumption at current time, and the step pf obtaining the real-time driving mileage of the motor vehicle according to the residual oil mass of the target and the average oil consumption of the target. The real-time motor vehicle driving mileage obtained with the method effectively reflects the driving distance of the current residual oil mass of the automobile, reliable information assistance is provided for a driver, and inconvenience brought to the driver due to the calculating error of the driving mileage is avoided.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a calculation method and device for the cruising range of a motor vehicle and an automobile. Background technique [0002] The cruising range of the car instrument can effectively reflect the driving distance of the car's remaining fuel, and provide reliable information for drivers, especially for people who drive long distances. [0003] In the prior art, a traditional mileage strategy is as follows: the mileage is related to the average fuel consumption of the vehicle within 10 kilometers. If the fuel consumption is high when driving in urban areas within 10 kilometers, the mileage is low; Internal high-speed driving, low fuel consumption, high cruising range. If you continue to switch between urban areas and high-speed driving, the cruising range will fluctuate, and the cruising range cannot accurately reflect the actual mileage of the vehicle. [0004] Another cruising ...
